Consider the given dataset from an employee database. For a given entry row, count column represents the number of data tuples having the values for department, salary, and status given in that row. For example, there are 15 instances with values of (department = sales, salary high, status-senior). Let status be the class label attribute, answer the following questions. Department Salary Status Count Sales High Senior 15 Sales Low Junior 20 Systems Medium Junior Marketing High Junior Marketing High Senior a. What is the value for the H(Status)? Where H(r) defines the entropy of r? 20 10 5 Consider the given dataset from an employee database.
